What caused my variatus to die? Warning: dead fish in pictures

[tzahroxi]

This happened overnight. She was completely fine and happened out of nowhere. The only thing i can think of is that she over ate. i typically feed more than i should sometimes cause some of the slower fish wont get to eat. she was really bloated when i found and everywhere i look says dropsy but her scales dont look raised. are they? sorry for so many picture of something unsettling but i wanted to make sure if anyone could spot what happened.
